The Leonids (/ ˈ l iː ən ɪ d z / LEE-ə-nidz) are a prolific annual meteor shower associated with the comet Tempel–Tuttle, and are also known for their spectacular meteor storms that occur about every 33 years. [5] The Leonids get their name from the location of their radiant in the constellation Leo: the meteors appear to radiate from ...
The Leonid meteor shower peaks around 17 November of each year. The Leonid shower produces a meteor storm, peaking at rates of thousands of meteors per hour. Leonid storms gave birth to the term meteor shower when it was first realised that, during the November 1833 storm, the meteors radiated from near the star Gamma Leonis. The last Leonid ...
This list of meteor streams and peak activity times is based on data from the International Meteor Organization while most of the parent body associations are from Gary W. Kronk book, Meteor Showers: A Descriptive Catalog, Enslow Publishers, New Jersey, ISBN 0-89490-071-4, and from Peter Jenniskens's book, "Meteor Showers and Their Parent ...
This coincidence means that past streams from the comet at perihelion are still dense when they encounter Earth, resulting in the 33-year cycle of Leonid meteor storms. For example, the 1833 meteor storm was created by the previous 1800 perihelion passage. [19]
The March Virginids are a minor meteor shower stream; the source of the Northern March Virginids is thought to be 1998 SJ70. [10] [dead link ] The Beta Leonids, lasting from February 14 to April 25, peaking around March 20 with three to four meteors per hour, were also referred to as the "March Virginids". [22]
Hundreds of thousands of kilometers long, the feature was discovered in 1998 as a result of scientists from Boston University observing the Leonid meteor shower. [1] [2] [3] The Moon is constantly releasing atomic sodium as a fine dust from its surface due to photon-stimulated desorption, solar wind sputtering, and meteorite impacts. [4]
Born in Brockport, New York, he was the son of Alonzo J. Howe, a professor at the old University of Chicago, and Julia M. Osgood. [1] During his youth he developed an interest in the stars, witnessing the spectacular Leonid meteor shower of November 1866. [2]
Juraj Tóth (born 28 March 1975) is a Slovak astronomer, discoverer of minor planets, and professor of astronomy at Comenius University in Bratislava, Slovakia. [2] [3]An expert in meteoroid fragmentation, he is known for his observations of the 1998 Leonid meteor shower from Modra Observatory, [4] which were later published in the journal Earth, Moon, and Planets.
